Ah you’re missing gettext that’s why. I’ll put a fix out for users without gettext.
Update: Also, it seems Windows LAMP setup is defaulted to putting notice and warning message on the page output (which makes no sense since the end-user is typically not the programmer).
Update 2: I pushed an update which should create the _() function which is the shorthand for gettext. This way, the app at least functions and outputs english strings if you are missing gettext. Let me know if this helps.
